To all whom it may concern."

Be-it known that we, BENJAMIN United States, whose respective residences are borough of Queens and borough of Brooklyn of the city of New York, in the State of New York, have invented certain new and useful Improvements in Hoisting and Dumping Mechanism for Cans, of which the following is a specification, reference being had to, the accompanying drawings,

' forming a part hereof.

lifting the cans over the sides ofthe vehicle. Automatic means for performin this work must, generally speaking, satis two im-' portant requirements, to wit, it must save gmany hours of labor and be sanitary, his

the principal object of the present invention to providean automatic hoisting and dum in'g .mechanism for cans which will 'satis these two principal requirements and, in addition, be of simple, inexpensive and ru god 1 30 construction, invariable in operation an especially eifective for use on motor vehicles where a source of power may be readily derived for elevating. the cans. More particularly, the invention has for other objects rovide a carrier for a can which may be. rawn up a track-way at the side of a motor vehicle and automatically tipped over the ibedumped as wil morefully appear hereinafter. In the open side of the housing d sides of the body for discharging the contents of the can. Still another object is to provide in association with the last-named means, an automatic power take-off which will insure the travel of the carrier for a predetermined distance only. Where the lmproved mechanism is adapted primarily for the hoisting and dumping of ash-cans, means will'be provided on the body for receiving the mouth of the can at the time of dumping and confining the dust so that it may not escape to the street.

These and other objects will appear more particularly hereinafter in connection with n mand ADAM ROSECRANS, both citizens of the through the track-way an l A NEW YORK. HOISTING AND DUMPING MiECHANISM FOR CANS.

The vehicle .awhich maybe of an P? roved form or desi is, in thelpre erred orm of the invention self-propellediand includes a transmission b from which e15 tends a lay shaft 0 for theconvenient takeofi of fower. On the vehicle a is mounted a body of siich design as may best serve the purpose for which the vehicle is intended, the

ody illustrated bein' welladapted' for the collection of ashes. o this man is prefe rred to close the top d'there'of and protherein'an upper extending housing d having'one side 0 n to. receive the can to may be hun a flexible dust curtain d which is engaged y the can at the time of dumping and serves to prevent the escape of dust. I

be built rack.

tending adjacent and longitudinally of the track-Ways and providing opposed flanges between which are disposed the guide rollers 71, k, at opposite sides of the can carrier-Z. This carrier Z is of generally semi-circular form as shownin Figure 7 and has a bottom plate Z on which the can to be dumped may be placed by the attendant. When in its lowermost'position in the track-ways g the carrier Z is placed at a convenient height to permit the can to be dumped to be placed thereon quickly and with little elfort by the attendant. If the can is placed on the carrier it is strappedthereto by any suitable securing means which will facilitate speed in fastening and unfastenin By way of example, as is illustrated in the drawings, a cord m which is anchored at one side of'the carrier and has a free end which may be quickly engaged by the attendant with a tlghtening device at the other side shown as a ivoted lever n movable over a rack n an adapted to be secured in adjusted posi tion by the pawl n carried with the lever and en aged releasably with teeth of the %n the cord m is the hook m which is engaged with the edge of the can before the tightening lever 41 is moved to draw the cord taut.

The can is elevated up the trackovays g by cables'o engaged with the carrier at opposite sides near its bottom and extending upwardly over sheaves p supported near the upper ends of the beamse from whence they may be carried downwardly to hoisting drums 0' respectively.- These hoisting drums 0 may be mounted under the frame of the vehicle and it may be convenient .to lead the cables 0 down the channels e i and over other sheaves 77' mounted at'the lower ends thereof before they are led on to the hoisting drums 0'. The drums 0 ma be carried on the lay shaft 0 from whic' power is obtained from the transmission bQ In order to limit the upward travel of the carrier Z under the power of the lay shaft 0 the latter has therein a clutch c by which the rotation of the drums 0' may be discontinued when desired. In the preferred embodiment the clutch c is preferably controlled automatically so 'that it will be thrown out after the carrier Zhas travelled a predetermined distance. Such automatic devices may include a worm 0 carried. on

the lay shaft 0 and engaged by a travelling worm gear indicated conventionally at c and connected with a slotted bar 0 which travels with the worm gear when the worm 0 is rotated. The operating handle 0 carried a stud 0 which rides in the slot 0 in the bar 0 so that the handle 0 is'moved in one direction or the other after the bar 0 has moved a predetermined distance and the stud c rests at one end of the slot or the other. f

carrier that the upper rollers i tend to ride Y along what may be termedthe lower face of the track-ways 9 while the lower rollers k tend to ride along what may be termed the upper face of the track-ways. The re-- sult is as indicated by the arrows in Figure 8 that the rollers 71 will always follow the straight sections of the track-ways 9 when the carrier is elevated,'whereas the lower rollers It will be drawn into the shunt portions g. of the track-ways when they reach that elevation. Continued movement of the cables 0 on the carrier Z at points below both of the rollers will serve to draw the lower rollers 70 to points above the upper rollers 73. A hook Z on the carrier engages the transverse dumping rod 7 when the can is in its the rollers i, it movin about the fulcrum in their respective trac -ways. The dumping position is indicated in dottedlines in Figure 5. At the time of dumping the mouth of the can is moved into the open side of the housing 03 on the body d and presses aside the flexible dust curtain d to an extent suflicient to permit the contents of the can to discharged into the body while the dust is confined by the joint action of the can and the curtain. The travel of the bar 0 and relation of its slot 0 to the stud 0 are such that the lever a will be thrown to unclutch the lay shaft 0 when the can has reached the position indicated in dotted lines in Figure 5. After the can has discharged its contents the attendant will move the handle 0 so as to throw the clutch 0 into reverse thereby revolving the drums o in the opposite direction while the carrier Z drops down the ways 9 under the influence of gravity, to loading position. The travel of the bar 0 will again be so timed as to move the handle 0 and throw a be made without departing from the spiritof the invention. The drawings show, in conventional form, suitable parts for performing the necessary functions in proper coordination to bring about the results sought, but other parts may be employed in somewhat different relations without 'changing the principles involved.

What we claim is: v

1. A hoisting and dumping mechanism for cans including in combination with the vehicle body, track-ways mountedat one side thereof and extending from points above the side walls of the bod downwardly and outwardly at one side 0 the body, a carrier for the can having two spaced rollers at-each hoisting and dumping mechanism for cans including track-ways mounted at one side of the vehicle body, 5 aced rollers mounted movably in said trac -ways, a can carrier supported on said rollers, cables connected with the lower portions of the carrier to elevate it and shunt track-ways commu-ni-' eating with said first-named track-ways adjacent the upper ends thereof, said hoisting cables serving to draw the lowermost of said rollers in said shunt track-ways to invert the carrier.
